Keith Murphy runs Fabulous Homes Heating & Air from Mohawk Street in College Area, a San Diego NATE-certified HVAC contractor serving the 92115 ZIP roughly a mile south of the SDSU campus. Murphy brings over 14 years of field experience to every service call and holds active NATE certification in air conditioning installation and heat pump service, a credential verified through the North American Technician Excellence testing program. Sealed ductwork testing is part of every new installation, because pest infiltration through unsealed register boots and flex-duct connections is a persistent problem in the area's older homes — a condition that Suncoast Pest Management frequently documents during termite inspections on the same properties. The shop installs Daikin ductless mini-split systems with a 12-year manufacturer warranty, handling both single-zone wall-mount units and multi-zone branch-box configurations for homes that lack existing ductwork. College Area's housing stock includes a high proportion of rental properties serving the university population, and Murphy's crew handles landlord-side system replacements on multi-unit buildings where shared condensing platforms must be sized for simultaneous peak-load operation across several apartments. Residential and commercial HVAC, ventilation, and solar energy system service round out the scope, with the solar tie-in covering hybrid heat pump water heaters and photovoltaic-offset AC installations. Kitchen and bathroom remodels that relocate supply registers or add return-air pathways require HVAC coordination before drywall goes up, and Murphy works directly with remodeling contractors at Coast Design & Build on duct-routing plans during the rough-in phase. The A+ Better Business Bureau rating reflects a complaint-free file, and Murphy's approach emphasizes written load calculations and equipment spec sheets delivered to the homeowner before any installation contract is signed. Each mini-split installation includes a vacuum pump evacuation to below 500 microns, nitrogen pressure testing of the line set, and a final charge verification against the manufacturer's subcooling target for the installed lineal footage.
